Title: Improvements in or relating to electric signalling systems
Inventor: MACKENZIE JOHN FRANCIS
IPC: H02J13/00
Filed: 1952-12-16
Abstract: 729,786. Electric selective signalling systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Nov. 5, 1953 [Dec. 16, 1952], No. 31833/52. Class 40 (1). A system for signalling over electric power lines comprises means for producing a series of audio-frequency pulses of different cadence frequency but each having equal on and off periods, and selectively combining the pulses for transmission over the power lines, the receiver comprising a circuit tuned to the A.F. followed by relays responding to the pulse rate frequencies for producing selected switching. As shown (Fig. 1) the signals are supplied through a transformer IT from an audio frequency motor alternator AFMA via tuned leads which are normally short-circuited by contactors CM1, CM2. These contactors are operated by a magnet CM whose energization is effected by the closure of contacts RCA, RCB, RCC, which are periodically opened and closed by a cadence generator (not shown) at different frequencies, the make-and-break time being equal for each contact. Thus, if RCA, RCB only are actuated by the cadence generator, a pulsed A.F. signal is sent to the H.T. lines, the pulse rate being the difference between the frequency of operation of contacts RCA, RCB. The pulses are transmitted through the distribution network and step-down transformer ST, and are fed from lines L3, N to coupled circuits C1, I1 and C2, I2, both tuned to the A.F., to a bridge rectifier RB, to produce corresponding unidirectional pulses which operate galvanometer relays GA; GB which are tuned to the same frequency. as contacts RCA, RCB respectively. Thus contacts GA1, GB1 will be jointly closed at certain instants, whereupon relay LR is energized, and locks mechanically, to close contact LR1, and connect the load L to the lines L3, N. The magnitude of the output signal from rectifier RB is limited by parallel, non-linear resistor NLR, and rectifier MR. In a similar manner, if contacts RCA, RCC are actuated at the transmitter, relays GA, GC are operated at the receiver to close contacts GA1, GC1, whereupon relay LR is operated in the opposite direction to remove the load L from the lines L3, N. The system may be extended to perform three operations by the addition of a further contact and galvanometer relay. Specification 593,378 is referred to.

Abstract: 1370547 Watches BERNHARD FORSTER 11 July 1972 [22 July 1971] 32307/72 Heading G3T A self-winding mechanism for a watch comprises a rotor 1 which fixedly carries a concentric drive pinion 3 and thus drives, when the rotor moves in the direction of arrow A, a reversing gear 4 and a gear 5 coupled to an output pinion 12. When the rotor moves in the direction of arrow B, the reversing gear 4 is uncoupled and a ratchet wheel 7 which is freely mounted on the ,pinion 3 is locked to the rotor by means of a pawl 9 pivoted thereon so that a gear ring 10 of the ratchet wheel drives a gear 11 fixed to the gear 5, thus rotating the pinion 12 in the same direction as before. The pinion drives a mainspring ratchet wheel (15), Fig. 2 (not shown) via gears (13, 14). To permit easy disassembly, the rotor 1, which is pivoted on a pin (2), is restrained axially by a finger 17 of a plate 16 over-lying the pinion 3.

Title: Improvements in or relating to elevating gear for guns
IPC: F41A27/24
Filed: 1927-12-01
Abstract: 303,626. Beardmore &. Co., Ltd., W., and Webster, T. H. Dec. 1, 1927. Mountings.-For bringing a heavy gun quickly to the loading position, a secondary elevating arc 7, loosely mounted on the gun trunnions 3, is operated by a hand or power loading- gear through a pinion 46. The loading -gear operates first to remove a locking bolt 16 from engagement with the main elevating-arc 1 by lever means 9, 11 linked to the secondary arc, the further rotation of the pinion 46 causing, the gun to move to the loading position shown, where it is held. by a bolt 28 engaging a stop 30 on the carriage. The main elevating arc 1 is loosely mounted on the trunnions, and can be adjusted for ranging purposes by a motor 43 operating a worm-driven pinion 33 through a clutch 41, which allows for hand operation through a wheel 39. When the loading arc 7 is locked to the elevating arc 1 by the bolt 16, the ranging movement of the gun results in an idle movement of the pinion 46 over the arc 7, since the shaft 61 of the hydraulic loading motor 62 is declutched from the pinion by the means shown in Fig. 5. This includes a spring 57 for normally holding the clutch 52, 53 in the off position, the shaft 55 carrying the clutch member 53 being moved by hydraulic pressure admitted to a cylinder 64 by pipes 74, 76 connected to the loading motor 62. The arrangement is such that the pinion 46 is only driven when the loading motor is energized for motion in either direction. A hand-gear 77 is movable laterally to engage the clutch member 52 when the loading gear is to be operated from a handwheel 80. The spring bolt 16 for locking the gun in the firing position is mounted on a bracket 13 on the gun cradle and is operated by a bell-crank lever 14 connected to the link 9, which is hinged to the arc 7. Movements of the lever 14 are conveyed by a link 21 and lever 26 to the bolt 28, which locks the gun in the loading position, the arrangement being such that, when the bolt 28 is released, the bolt 16 is energized and vice versa. Hydraulic buffers 18, 31 prevent shock when the gun is brought against, the elevating and loading stops respectively.
